Summary

The digital flood-inundation maps included in this data release were developed for a 16.4-mile reach of the Yellow River from 0.5-mile upstream of River Drive to Centerville Highway (Georgia State Route 124), Gwinnett County, Georgia (Ga.) to depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at two U.S. Geological Survey (USGS) streamgages in the mapped area. The maps for the 9.0-mile reach from 0.5-mile upstream of River Drive to Stone Mountain Highway (US Route 78) are referenced to the Yellow River, near Snellville, Georgia (Ga.; station 02206500), and the maps for the 7.4-mile reach from Stone Mountain Highway to Centerville Highway are referenced to the streamgage Yellow [...]

Purpose

This dataset was created to support the development of flood-peak inundation maps for the Yellow River in Gwinnett County, Georgia. Geographic Information System (GIS) shapefiles represent the modeled flood inundation extents of a 9.0-mile reach of the Yellow River from 0.5-mile upstream of River Drive to Stone Mountain Highway, and a 7.4-mile reach of the Yellow River from Stone Mountain Highway to Centerville Highway, Gwinnett County, Georgia. These flood inundation extents are for 1.0-foot intervals referenced to the water surface elevation and ranging from stage 18.0 to 33.0 feet (water surface elevation 819.1 to 834.1 feet) for streamgage 02206500, and stage 13.0 to 29.0 feet (water surface elevation 7325 to 748.5 feet) for streamgage 02207120. The flood-inundation maps will be used on the U.S. Geological Survey Flood Inundation Mapper website. GIS raster files represent the inundation depths corresponding to each flood extent elevation value for each of the two river extents.
